reparent cefBrowser after creation Linux

[calkins]

Hi all,

Is it possible to reparent the cefBrowser after it has been created? Currently I am creating the browser in the standard way as shown below by passing in the XID of its parent to the windowInfo variable. For our use case we need to reparent the browser when our main process quits but cannot find a way to do so.

Code: Select all

CefWindowInfo windowInfo;
CefRect rc(0, 0, 320, 320);
windowInfo.SetAsChild(parentXID, rc);
CefBrowserSettings browserSettings;
CefBrowserHost::CreateBrowser(windowInfo, this, "", browserSettings, nullptr, nullptr);

An XID is returned via browser->GetHost()->GetWindowHandle(). You will need to reparent that. See example here: https://github.com/chromiumembedded/cef ... tk.cc#L132

This didnt quite seem to solve our problem. When our application closes the variable xwindow_ is being set to None and we return here: https://sourcegraph.com/github.com/chro ... x11.cc?L15

This is causing windowDestroy to not be called and as a result OnBeforeClose to not be called. From the code we cant find how xwindow_ is being set to None, do you have a clue as to why this could be? Our thought was reparenting would help but it doesnt.

I don't think your link is working as intended. What code line did you intend to reference?

My bad. CefWindowX11::Close() function line 151. Our application is returning on line 153.
